What is an essential requirement for any CNG cargo tank?

An essential requirement for any CNG cargo tank is that it must have a recent test certificate. This certificate ensures that the tank has been properly inspected, tested for structural integrity, and meets safety standards for transporting compressed natural gas. Regular testing is critical to avoid leaks or failures that could lead to hazardous situations, including explosions or environmental contamination. The requirement for a recent test certificate is a vital safety measure that underscores the importance of compliance with regulatory standards and maintaining operational safety protocols for CNG transport.

While considerations like rust resistance, color coding for identification purposes, and size limitations may play roles in the overall safety and regulatory compliance of CNG operations, the absence of a valid test certificate would mean that the tank is not certified for safe use, making this requirement particularly crucial.
